Along with Tim Cahill, Milligan is in line to be one of two Australians to have featured in four FIFA World Cup squads.

He won his first selection in 2006 after standing out for Sydney FC in the inaugural season of the Hyundai A-League and followed a mature 2007 AFC Asian Cup campaign with stints at Newcastle Jets, Shanghai Shenhua and JEF United Chiba.

Milligan's was well-travelled by the time of his move to Melbourne Victory in January 2012 and put the experience to good use in a three and a half season spell that culminated in Grand Final glory and the Joe Marston Medal in 2015.

The adaptable, mobile midfielder had a second stint with Victory after more than 40 appearances at Baniyas, but left again for Saudia Arabian side Ah-Ahli in January.

Unused in both 2006 and 2010, Milligan - an occasional national team captain - received his first FIFA World Cup minutes in 2014, playing the full match against Chile.

Hyundai A-League connection:

Named on the bench in the PFA's Hyundai A-League Team of the Decade for 2005-2015, Milligan's combined nine seasons with Sydney FC, Newcastle Jets and Melbourne Victory rank him among the greats of the competition.
